Convergent evidence indicates that abnormalities in the innate immune system may be pertinent to the pathogenesis, phenomenology, and possible treatment of several mental disorders. In keeping with this view, the targeting of interleukin-6 with the human monoclonal antibody sirukumab may represent a possible treatment and disease modification approach, for adults with brain-based disorders (e.g., major depressive disorder). A PubMed/Medline database search was performed using the following search terms: sirukumab; anti-IL-6; IL-6; major depressive disorder; inflammation...

Patulin is the main mycotoxin contaminating apples. During the brewing of alcoholic beverages, this mycotoxin is degraded to ascladiol, which is also the last precursor of patulin. The present study aims (1) to characterize the last step of the patulin biosynthetic pathway and (2) to describe the toxicity of ascladiol. A patE deletion mutant was generated in Penicillium expansum. In contrast to the wild strain, this mutant does not produce patulin but accumulates high levels of E-ascladiol with few traces of Z-ascladiol...

TP53 undergoes multiple RNA-splicing events, resulting in at least nine mRNA transcripts encoding at least 12 functionally different protein isoforms. Antibodies specific to p53 protein isoforms have proven difficult to develop, thus researchers must rely on the transcript information to infer isoform abundance. In this study, we used deep RNA-seq, droplet digital PCR (ddPCR), and real-time quantitative reverse transcriptase PCR (RT-qPCR) from nine human cell lines and RNA-seq data available for tumors in The Cancer Genome Atlas to analyze TP53 splice variant expression...

Muscle activity monitoring or Electromyography (EMG) is a useful tool. However, EMG is typically invasive, expensive and difficult to use for untrained users. A possible solution is textile-based surface EMG (sEMG) integrated into clothing as a wearable device. This is, however, challenging due to (i) uncertainties in the electrical properties of conductive threads used for electrodes, (ii) imprecise fabrication technologies (e.g., embroidery, sewing), and (iii) lack of standardization in design variable selection...

New, more effective and less toxic medications are desperately needed for patients with partial (focal) epilepsy. Many hurdles prevent the appropriate study of promising compounds. One of these hurdles is the gap between Phase I and Phase II-the expensive proof of concept to suggest that human trials in partial seizure patients will be successful. A short-cut, the photoparoxysmal response (PPR) model has recently been used to increase confidence in moving a compound into Phase II and III. This shortcut has substantial limitations...

Academic researchers who seek to publish their work are confronted daily with a barrage of e-mails from aggressive marketing campaigns that solicit them to publish their research with a specialized, often newly launched, journal. Known as predatory journals, they often promise high editorial and publishing standards, yet their exploitive business models, poor quality control, and minimal overall transparency victimize those researchers with limited academic experience and pave the way for low-quality articles that threaten the foundation of evidence-based research...

OBJECTIVES: Integrating a behavioral health consultant (BHC) into primary care is associated with improved patient outcomes, fewer medical visits, and increased provider satisfaction; however, few studies have evaluated the feasibility of this model from an operations perspective. Specifically, time and cost have been identified as barriers to implementation. Our study aimed to examine time spent, patient volume, and revenue generated during days when the on-site BHC was available compared with days when the consultant was not...

Optogenetic methods to modulate cells and signaling pathways via targeted expression and activation of light-sensitive proteins have greatly accelerated the process of mapping complex neural circuits and defining their roles in physiological and pathological contexts. Recently demonstrated technologies based on injectable, microscale inorganic light-emitting diodes (μ-ILEDs) with wireless control and power delivery strategies offer important functionality in such experiments, by eliminating the external tethers associated with traditional fiber optic approaches...

With increasing amounts of information available, modeling and predicting user preferences-for books or articles, for example-are becoming more important. We present a collaborative filtering model, with an associated scalable algorithm, that makes accurate predictions of users' ratings. Like previous approaches, we assume that there are groups of users and of items and that the rating a user gives an item is determined by their respective group memberships. However, we allow each user and each item to belong simultaneously to mixtures of different groups and, unlike many popular approaches such as matrix factorization, we do not assume that users in each group prefer a single group of items...

There have been rapid advances in technologies over the past decade and virtual reality technology is an area which is increasingly utilized as a healthcare intervention in many disciplines including that of Medicine, Surgery and Psychiatry. In Psychiatry, most of the current interventions involving the usage of virtual reality technology is limited to its application for anxiety disorders. With the advances in technology, Internet addiction and Internet gaming disorders are increasingly prevalent. To date, these disorders are still being treated using conventional psychotherapy methods such as cognitive behavioural therapy...

BACKGROUND: The incidence of human immunodeficiency virus (HIV) in repeat blood donors has been estimated using seven methods. Although incidence is always calculated as cases per person-time, approaches to selecting cases and calculating person-time vary. Incidence estimates have not been compared among methods. STUDY DESIGN AND METHODS: The seven methods were compared in a simulation study. Because three methods used information from donations made before an estimation interval, 8 years of donation and infection history were simulated, and Years 7 and 8 were treated as the estimation interval for all methods...

Chronic pulmonary hypertension (PH) is associated with right ventricular failure and high mortality regardless of the underlying disease. Currently, therapies can improve clinical outcomes in specific subsets of patients, but have little impact on the progression of pulmonary vascular remodeling. Upon new advances in vector development and delivery techniques, gene therapy is a novel strategy in this field with the potential of overcoming the main limitations of approved drug therapies: modulation of novel anti-remodeling targets and selective pulmonary vasculature targeting with minimal systemic effects...

Gene therapy holds great promise as a targeted treatment of cardiovascular diseases, which remain a major cause of morbidity and mortality in contemporary societies. Selection of the appropriate vector delivery method is critical for efficient transduction in the myocardium. Direct myocardial delivery is a feasible and effective method that has been shown to exhibit enhanced gene expression compared to coronary infusion and pericardial delivery. It is one of the most widely used gene transfer methods in both animal studies and clinical trials...

Percutaneous antegrade coronary injection is among the least invasive cardiac selective gene delivery methods. However, transduction efficiency is quite low with a simple bolus antegrade injection. In order to improve the transduction efficiency using antegrade delivery, several additional approaches have been proposed.In this chapter, we briefly discuss important elements associated with intracoronary delivery methods and present protocols for three different catheter-based antegrade delivery techniques in a preclinical large animal model...

Altering expression of specific genes in rodent models allows the dissection of various pathways involved in various disease states. Advances in gene transfer technologies produced vectors with tissue specificity, various time courses, increasing or knocking down genes in an externally controlled fashion. To achieve this goal, appropriate vector delivery method is essential for successfully conducting experiments. In this chapter, we focus on cardiac gene transfer in rodents that can be employed for delivering both viral and nonviral vectors...

Over the last decade a previously unappreciated mechanism of gene regulation has been uncovered that is mediated by a large class of small noncoding RNAs known as microRNAs (miRNAs), and this mechanism is utilized by organisms ranging from plants to humans. MiRNAs are important downregulators of gene expression and are seen to be dysregulated in disease development. Thus inhibition of aberrantly upregulated miRNAs as a therapeutic approach has become a promising field.Many models of miRNA inhibitors currently exist, with decoy models being the most successful in current research...

During the last decade, there has been a significant progress toward clinical translation in the field of cardiac gene therapy based on extensive preclinical data. However, despite encouraging positive results in early phase clinical trials, more recent larger trials reported only neutral results. Nevertheless, the field has gained important knowledge from these trials and is leading to the development of more cardiotropic vectors and improved delivery systems. It has become more evident that humans are more resistant to therapeutic transgene expression compared to experimental animals and thus refinement in gene delivery tools and methods are essential for future success...
